Every part of a bicycle (frame, wheels, cranks, handlebar, gears, tires, etc.) has a service life cycle that depends on many factors such as: the technology and materials used; the cyclist’s weight and power; care and maintenance; how often, how and where the bicycle is used, the use of harsh cleaners, and external factors like impacts, crushing or falls.

Components are subject to normal wear, to surface wear, and to a form of wear called “fatigue” that consists in progressive deterioration of the structure’s mechanical properties due, initially, to the presence of an almost invisible micro-fracture that grows overtime, to the point of weakening the component and causing it to give way suddenly when the crack becomes sufficiently large.

Initially, fatigue is difficult to see, which makes it insidious. To reduce the risk of an accident, it is important to monitor wear and spot early signs of fatigue before they can cause a sudden failure. To improve safety, have all components frequently inspected at an authorized Wilier Triestina assistance centre to identify wear, cracks, micro fractures, corrosion, deformation, dents, paint damage and any other indication of a problem before they can cause product failure.

Should the product become damaged due to a fall or in the presence of obvious damage due to other causes:

  • Immediately stop using the bicycle
  • Contact the authorized dealer where the product was purchased for necessary safety checks. For products purchased on line from, contact Wilier Triestina S.p.A. immediately using the contact forms on the website


In the event of accidents or impacts involving the frame or a component, forces applied to the component could irreparably damage the structure and cause breakage during subsequent use.

Any product that is worn, has lost its structural integrity or shows any sign of fatigue or damage must be replaced immediately to prevent accidents and serious injury to the consumer. The following parts are subject to normal wear from use: bearings (bottom bracket, headset, hubs), sheaths, cables, tires, tubulars, inner tubes, rims, brake pads/shoes, chains, chainrings, cassettes and saddles.

Improper use of the bicycle is risky, and factors such as poor maintenance, lack of frequent inspections, poor visibility, darkness or rain can greatly increase these risks. Proper maintenance, frequent inspections, wearing a helmet and high visibility clothing, lights, rear view mirrors, horns and careful riding help to reduce risks, though they cannot eliminate them altogether.



Wilier Triestina S.p.A. reserves the right to modify or cancel these warranty conditions at any time without notice to end consumers.
